Application March 1, 1940, Serial No. 321,627

` 4 claims. (o1. 24o-7s) f This invention relates to improvements in lighting xtures.

The main object of the invention is to provide an eiiicient lighting fixture for a tubular source of light.

A further object of the invention is to provide a lighting fixture for a tubular source of light with means for regulating the concentration of illumination expeditiously and safely.

A further object of the invention is to provide for the aforementioned purposes 4an economical and simple construction which can be readily manufactured and assembled.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawing in which like numerals are employed to designate like parts throughout the same.

Fig. l is a front elevational view of the invention,

Fig. 2 is a view in section taken along the line 2-2 of Fig. 1, and,

Fig. 3 is a perspective view with parts detached.

While the invention is susceptible of various modifications and alternative constructions, it is here shown and will hereinafter be described as embodied in an illustrative form but it is not intended that the invention is to be limited thereby to the specic construction but it is intended to cover all modifications and alternative constructions falling within the spirit and'scope of the invention.

Referring to the drawings, a tubular source of light I Il is mounted between a pair of sockets II which are secured partly within and partly without the housing I2 by means of screws I3. One of the sockets has a receptacle for an enclosed starter switch I4 which together with encased choke coll I5 constitute parts of the wiring v circuit.

yreflector surfaces on either side. Whereas tubular lamps of this type are usually mounted on either fiat or concave surface. this invention embodies a convex surface. The rays oi' light that emanate upwardly from the tubular lamp strike the convex surface above it and are diffused either downwardly or against the reflecting surfaces von either side which in turn direct those rays downwardly. Rays that emanate sidewise are likewise reflected downwardly. By adjustment of the position of the side reectors, the illumination may be concentrated at will.

Both of the side reflecting surfaces and convex surface of the housing are preferably covered with white enamel finish.

I claim as my invention:

1. A lighting xture comprising, in combination, a support having an outer convex reiiecting surface, said support carrying a light source, a

pair of adjustable arcuate-shaped wings pivoted l' to opposite ends of, and flanking, the support, the inner sides of the wings having concave reecting surfaces and the inner edges of the concave surfaces pivoting on a radius substantially equal to the radius of the support so that there is substantially no space behind the light source without a reflecting surface for various positions of the wing portions. f

2. A lighting fixture comprising, in combination, a housing having an outer convex reflecting surface, electrical sockets disposed within opposite extremities of and depending outwardly from the housing, a source of light mounted in the sockets, a pair of adjustable arcuate-shaped wings pivoted to opposite ends of, and flanking, the housing, the inner sides of the wings having concave reflecting surfaces and the inner edges of the concave surfaces pivoting ori a radius substantially equal to the radius of the support so that there is substantially no spa.e behind the light source without a reflecting surface for various positions oi the wing portions.

3. A lighting fixture comprising acylindrlc convex reflecting support, a pair oi concave reflecting wings, each of said wings having a circular disc-like terminal at opposite ends, the terminals having a diameter substantially equal to the diameter of the support and their central axes coinciding with the axis of the support, means for pivotally supporting said terminals in overlapping relationship to opposite ends of the support, and a cylindrical source of light carried bythe support parallel thereto and disposed between the wings.

4. A lighting fixture comprising a cylindric convex reecting housing, a cross member fixed to each end of the housing, a pair of concave reflecting wings, each of said wings having a circular disc-like terminal at opposite ends, the terminals having a diameter substantially equal to the diameter of the housing and their central f ,axes coinciding with the axis of the housing,
